Description

Technical Field

[0001] This utility model relates to the technical field of smelting furnaces for processing fused alumina, and in particular to a smelting furnace for processing fused alumina. Background Technology

[0002] In the field of fused alumina smelting, the hydraulic support structure of traditional tilting furnaces suffers from insufficient rigidity and stress concentration at connection nodes, which leads to a shortened mechanical fatigue cycle and an increased risk of structural instability, becoming a key bottleneck restricting the improvement of equipment production efficiency.

[0003] Therefore, it is essential to provide a smelting furnace for processing electrofused corundum to address the shortcomings of existing technologies. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a smelting furnace for electrofused corundum processing. This invention utilizes a symmetrical arc-shaped abutment plate structure driven by a bidirectional ball screw to form a dual-point stress-dispersing support for the root of the discharge cone tube in the smelting furnace body. This effectively suppresses stress concentration and prevents equipment deformation during the tilting process of the smelting furnace body. Electric telescopic plates A and B, in conjunction with rectangular slide rails, can form an L-shaped bidirectional adjustment structure, further adjusting the position of the bidirectional ball screw in both directions. The bidirectional ball screw drives two screw nuts to move in opposite directions, causing the arc-shaped abutment plate to tightly clamp the root of the discharge cone tube, preventing stress concentration points and helping to improve the fatigue life of key support points. This provides stable support for the smelting furnace during tilting operations, meeting the needs of industrial production capacity.

[0005] The above-mentioned objectives of this utility model are achieved through the following technical means.

[0006] A smelting furnace for processing fused alumina is provided, including a furnace body, an adjustable support mechanism installed at the bottom of the furnace body, and a material holding bucket installed on one side of the adjustable support mechanism.

[0007] Specifically, the adjustable support mechanism includes a support base, an arc-shaped guide rail installed above the support base, a slidably mounted smelting furnace body above the arc-shaped guide rail, and an electric telescopic column and a multi-dimensional adjustable support assembly installed on both sides of the smelting furnace body, with the multi-dimensional adjustable support assembly and the electric telescopic column respectively installed on both sides of the support base.

[0008] Preferably, the multi-dimensional adjustable support assembly includes a rectangular slide rail, which is installed between the support base and the material container. An electric telescopic plate A is slidably mounted on the rectangular slide rail, and an electric telescopic plate B is horizontally mounted at the bottom of the electric telescopic plate A. The fixed end of the electric telescopic plate B is installed on the rectangular slide rail near the end of the material container.

[0009] The top of the electric telescopic plate A is equipped with a screw support frame. A bidirectional ball screw is movably mounted on the screw support frame via bearings. Two screw nuts are driven on the bidirectional ball screw. An arc-shaped abutment plate is installed above each screw nut. The two arc-shaped abutment plates symmetrically abut against one side of the smelting furnace body relative to the central axis of the smelting furnace body.

[0010] The smelting furnace body includes the furnace body itself, which is a cylindrical structure. A semi-circular sliding base is installed at the bottom of the furnace body, and the bottom of the semi-circular sliding base is slidably installed with an arc-shaped guide rail. A furnace cover is installed on the top of the furnace body.

[0011] Three electrode holes are opened at equal angles on the furnace cover, and an electrode is movably installed at each electrode hole. Lifting brackets are installed on the outside of the three electrodes. A balance support column is installed on one side of the furnace body, and the bottom of the balance support column abuts against the top of the electric telescopic column.

[0012] The other side of the furnace body is connected to a discharge cone pipe. Two arc-shaped abutment plates are symmetrically snapped at the connection between the outer side of the discharge cone pipe and the outer side of the furnace body. The discharge end of the discharge cone pipe is located above the material container.

[0013] This invention utilizes a symmetrical arc-shaped abutment plate structure driven by a bidirectional ball screw to form a dual-point stress-dispersing support for the root of the discharge cone tube in the smelting furnace. This effectively suppresses stress concentration and prevents equipment deformation during the tilting process of the smelting furnace. Electric telescopic plates A and B, in conjunction with rectangular slide rails, form an L-shaped bidirectional adjustment structure, further adjusting the position of the bidirectional ball screw. The bidirectional ball screw drives two screw nuts to move in opposite directions, causing the arc-shaped abutment plate to tightly clamp the root of the discharge cone tube, preventing stress concentration points and improving the fatigue life of key support points. This provides stable support for the smelting furnace during tilting operations, meeting the demands of industrial production capacity. Attached Figure Description

[0040] The present invention will be further described in conjunction with the following embodiments.

[0041] Example 1.

[0042] like Figure 1-2 As shown, a smelting furnace for electrofused corundum processing includes a smelting furnace body 1, an adjustable support mechanism 2 installed at the bottom of the smelting furnace body 1, and a material holding bucket 3 installed on one side of the adjustable support mechanism 2.

[0043] like Figure 1-2As shown, the adjustable support mechanism 2 includes a support base 4, an arc-shaped guide rail 5 is installed above the support base 4, a slidably mounted smelting furnace body 1 is installed above the arc-shaped guide rail 5, an electric telescopic column 6 and a multi-dimensional adjustable support assembly 7 are respectively installed on both sides of the smelting furnace body 1, and the multi-dimensional adjustable support assembly 7 and the electric telescopic column 6 are respectively installed on both sides of the support base 4.

[0044] like Figure 1-2 As shown, the multi-dimensional adjustment support assembly 7 includes a rectangular slide rail 8, which is installed between the support base 4 and the material container 3. An electric telescopic plate A 9 is slidably installed on the rectangular slide rail 8. An electric telescopic plate B 10 is horizontally installed at the bottom of the electric telescopic plate A 9. The fixed end of the electric telescopic plate B 10 is installed on the rectangular slide rail 8 near the end of the material container 3.

[0045] like Figure 1-2 As shown, a screw support frame 11 is installed on the top of the electric telescopic plate A 9. A bidirectional ball screw 12 is movably installed on the screw support frame 11 via bearings. Two screw nuts 13 are driven and installed on the bidirectional ball screw 12. An arc-shaped abutment plate 14 is installed above each screw nut 13. The two arc-shaped abutment plates 14 are symmetrically abutted against one side of the smelting furnace body 1 relative to the central axis of the smelting furnace body 1.

[0046] like Figure 1-2 As shown, the smelting furnace body 1 includes a furnace body 15, which is a cylindrical structure. A semi-circular sliding base 16 is installed at the bottom of the furnace body 15. The bottom of the semi-circular sliding base 16 is slidably installed with an arc-shaped guide rail. A furnace cover 17 is installed on the top of the furnace body 15.

[0047] like Figure 1-2 As shown, three electrode holes 18 are opened at equal angles on the furnace cover 17, and an electrode 19 is movably installed at each electrode hole 18.
